Consider merging with magnesium in biological systems
There is a much longer article (mostly by me) on magnesium in biology at magnesium in biological systems
I think someone could merge the two to give a better starting point for this article. However with that done this article is likely to be outside the scope of the MCB project. Being then a more general article on magnesium ranging across mol bio, physiology etc.
With articles merged an animal physiology section should be written by someone who knows more that I do. This should be a general physiology section and NOT a human health section which has it proper place elsewhere.

I notice, many of these nutrition articles have a bias towards plant sources. What are some animal sources of magnesium? —Preceding unsigned comment added by 22.214.171.124 (talk) 23:44, 10 April 2008 (UTC)
Good for insomnia?
"Not enough magnesium can lead to hypomagnesemia as described above, with irregular heartbeats, high blood pressure (a sign in humans but not some experimental animals such as rodents), insomnia and muscle spasms (fasciculation). However, as noted, symptoms of low magnesium from pure dietary deficiency are thought to be rarely encountered." Does this mean that extra magnesium doesn't help with insomnia, unless you have a deficiency, which is uncommon? There is some talk about how magnesium pills is supposed to help with sleep, something should be mentioned about that. If it works or not and so on. Ran4 (talk) 08:18, 7 August 2008 (UTC)
These sections cherry-pick a few primary sources and fail to cite reviews, this isn't acceptable per WP:MEDRS. Reviews on this topic (such as PMID 16235322) give no support to the view presented in this text. Tim Vickers (talk) 03:37, 12 May 2009 (UTC)

According to a recent online survey, approximately 30% of parents give their autistic children a supplement of magnesium and vitamin B6 (Green 2006). There are conflicting studies as to whether or not this is an effective therapy for autism (Martineau 1985, Tolbert 1993, Findling 1997, Lelord 1981). There is no standardization of what dosages of magnesium and vitamin B6, nor are there standards as to which preparations of magnesium should be used. Varying doses used in popular practice may be confounding the results of scientific studies. Magnesium supplementation aims to normalize low levels in tissues, thus appropriate assays, such as erythrocyte magnesium measurements, should be used in dose ranging studies.
Mousain-Bosc and colleagues (2006) showed that children with autism - pervasive developmental disorder (PDD) (n = 33) had significantly lower red blood cell magnesium levels than controls (n = 36). Intervention with magnesium and vitamin B6 (pyridoxine) reduced PDD symptoms in 23 children out of 33, stereotyped restricted behavior (18 children), and abnormal/delayed functioning (17 children); it improved social interactions in 23 children and communication in 24 children.
Attention deficit hyperactivity disorder
Mousain-Bosc and colleagues (2006) showed that children with attention deficit hyperactivity disorder (ADHD) (n = 46) had significantly lower red blood cell magnesium levels than controls (n = 30). Intervention with magnesium and vitamin B6 (pyridoxine) reduced hyperactivity, hyperemotivity/aggressiveness and improved school attention.
Consider merging magnesium deficiency (agriculture) into here
The above short article is about magnesium deficiency in soils and plants, which is mostly (but not quite all) what THIS article is about. The human magnesium deficiency stuff is collected mostly at Magnesium deficiency (medicine) and Hypomagnesemia. I don't have a strong desire to merge plant and animal deficiency articles, because their mechanisms are so different. If there's to be an article about mechanisms of magnesium handling common to all living organisms, it should remain this one. The magnesium deficiency (agriculture) could easily be absorbed into the plant section of magnesium in biology (here). Meanwhile, hopefully it will be expanded eventually (perhaps with some material summarized in this article and moved to the plant article?)
- Okay, after 4 months of no comment, the old magnesium defiency article is now magnesium deficiency (agriculture). Sorry for the bad pagemove mechanism. SBHarris 20:54, 8 March 2011 (UTC)
Is magnesium needed for teeth as well as bones?
As a male sufferer of osteoporosis, I have long understood that magnesium is an important element for our bones, and this is certainly implied in the paragraph that states that magnesium deficiency can result in osteoporosis. However, isn't it also needed for our teeth? I am not an expert in magnesium deficiency, so do not wish to edit the article myself, but if any one knows about these things, the paragraph on human health could spell out more clearly how magensium is an important element for both teeth and bones.

Is one to understand that magnesium compounds other than MgCl2 do NOT have hypotensive effects? — Preceding unsigned comment added by 2602:306:CF99:2080:40D2:BF5A:6E42:4B33 (talk) 18:04, 1 September 2015 (UTC)
bioavailability in food
In the area of nutrition supplements, Magnesium oxide is infamous for being very cheap and common but having extremely low bioavailability, and thus nearly useless for nutrient purposes. Most other Magn supplement chemical forms are supposed to be much more bioavailable, at about 30%. What form is Magnesium in, in common foods, and what is the bioavailability in various foods -- is there significant variation in this?-126.96.36.199 (talk) 18:36, 6 September 2016 (UTC)
list of foods
The current article list of foods:
- "Following are some foods and the amount of magnesium in them:
- Black-eyed peas (1/2 cup) = 45 mg
is rather random and pitiful. It is also unsourced.
Many better versions are available. Here is a reputable source:
- https .. ods.od.nih.gov/factsheets/Magnesium-HealthProfessional/
small intestines primary site for Magnesium absorption
This source: www.ancient-minerals.com/magnesium-sources/absorption/
says that in the human body most magnesium absorption occurs in the small intestines. It seems to include some respectable sources. If this is a true fact it would be worth mentioning in the article.-188.8.131.52 (talk) 19:21, 6 September 2016 (UTC)
